curve and this causes a portion of the water to be forced out to thesides and to emerge from the nozzle in aline substantially at rightangles to the axis of the opening 5 as hereafter more fully explained.The remaining portion of the water will be forced upwardly.

plate is to be adjusted so as to obtain the most desirable results.

It will be noted, particularly by reference to Figure 6, that that partof the deflector plate which lies within the stream path extends at anangle thereto at the lower portion thereof, and that the surface of saidplate changes its direction within the stream path,

so that the upper portion of the plate changes I its angular directionand above the point- 18 the sides of the spray with great force.

creased so that a greater area it takes an opposite inclination, stillwithin the stream path. Accordingly, the lower or angular portion of theplate will deflect the stream upwardly while the upper portion willdeflect the stream laterally in substantially all directionstransversely to the axis of the stream. The upper or transverse portionof the plate, acting by itself, would deflect the stream in alldirections transversely'of the axis; i. e. downwardly as well aslaterally and upwardly. The action of the angular portion of the plate,however, by deflecting the lower portion of the stream upwardly, notonly counteracts and prevents thisdownward deflection, but is itselfcounteracted thereby, with theresult that the water is forced or: at

s a consequence, any downward spray of water is entirely eliminated sothat there is no erosion of the ground around the spray. At the sametime the sidewise energy of the spray is inmay be covered, as shown inFigure 5. i

It will further be seen that the deflector not only has a part (17-18)extending in a general direction along the stream path, or morespecifically diagonally therein and there-along, but a deflector part(1819) extends at an opposite inclination to the stream path close to asmall aperture in the nozzle in order to deflect. the stream. Moreover,as pointed out'above, the direction of the deflector changes in thestream path, with the result that the stream is deflected laterally andupwardly within the desired fieldor area.

The nozzle is j ournalled for free movement in its support about theaxis of the nozzle and the stream path; this is accomplished byproviding a comparatively rigid bearing 13 between the legs 11, so that.the screw 12 can be tightened in order to leave the strap sufficientlyloose in order to leave the nozzle free. This is advantageous, becauseany twisting of the hosewill permit the nozzle to move freely therewith,without disturbing the alinement of the nozzle aperture with thedeflector and without tearing the support loose. The frictional fit ofthe deflector between the legs and within the support furthermorepermits ready adjustment of the deflector without disturbing themounting, while the frictional fit provides means for retaining thedeflector in adjusted position.

From the above it will appear that I have provided a simple spray nozzlethat can be cheaply made and easily assembled, and which is soconstructed that it will throw the water along a substantially straightline along one side of the area sprayed; thus making it especially welladaptedioruse in spraying parkings and other parts of lawns adjacent tosidewalks. g It is obvious that various changes may be made in detailsof construction without departing from the spirit of this invention; itis, therefore, to be understood that this inven tion is not to belimited to the specific details shown and described.
